I've got a story I'm working on where the three main characters are teens (and they later get joined by a fourth kid). I need to get some second opinions on the names for the MCs and their families.

Adeline, aka "Addie" (one of the MCs, 13-year-old cisgendered female)
Ciara (Addie's older sister, I wanna say she's in her 20s)
Corynn (Addie's younger sister, 7 years old)
I also need to come up with a last name for these three, and names for their parents.

Charlie (another MC, 15 or 16 years old. Not too clear on whether Charlie is a genderqueer female who's birthname is "Charlene" or if zie is MTF. Either way, Charlie is slightly to the feminine side of the gender spectrum, but not by very much.) I also need to come up with her last name.

Lyra Eponine or Elizabeth "Beth" Eponine (another MC, 14 or 15 years old.) No matter what, her middle name is going to be Eponine, and her first name will be the name of a different literary character. The idea is that her mom gave her and her sisters each literary references for names.
Emma Harriet (Lyra/Beth's little sister)
Morgan Bianca or Morgan Hester (and yes, Hester being a potentially embarrassing middle name is intentional on my part). She's Lyra/Beth's older sister.
For Lyra/Beth's last name, I've narrowed it down to Einarsson, Hall, Nyström, or Norling. Any other suggestions are welcome, though. I'm leaning toward Germanic or Scandinavian for her name, preferrably Swedish or Norwegian.

For the fourth teen who joins up with them later, I'm thinking of having her name be Penelope, but she would go by "Penny."
